' Application filed December 14, 1883. No model.) I

To all whom it may concern Be it known that we, WILLIAM BENNETT RIOKMAN, residing at London, England, and- RICHARD PINTsoII and OSKAR PINTSCH, both 5, residing at Berlin, Germany, have invented an Improved Flash-Light for Sea-Lanterns, 'of which the following is a full, clear, and exact description, reference being made to the ac.- companying drawings. V I Sea-lanterns, especially such as'are carried by buoys and light-ships, are frequently so situated that it is desirable to provide them'with flash-lights-that is to say,with' lights that can be seen at intervals only. This we obtain in a gas-light by interrupting the supply of gas at intervals, for which purpose we employ a device which we interpose between the lantern and the pressure-regulator, said device being in substance a vessel having movable walls, so that its contents will be variable. From this vessel the main burners of thelantern are supplied with gas, and the movement of its walls, which takes place in filling and emptying this vessel, we utilize for the purpose of temporarily 2 5 closing the gas-supply to the burners, as hereinafter more clearly described. The burners are all relighted by a constant igniting-flame, which is not interfered with by the apparatus which regulates the display of light.

Figure 1 in the accompanying drawings is a vertical central section of thelower part of the lantern having our improvement. I Fig. 2 is a top view of the same. view, partly in section, of the apparatus for 5 regulating the supply of gas to the lightingburners; and Fig. 4 is a central section of the same, Figs. 3 and 4: being on a larger scale than Figs. 1 and 2.

The mechanism necessary for controlling the 0 supply of gas to the main burners is preferably placed in the vessel B, which is protected by the surrounding Walls of the lantern from all external injurious influences. On top this vessel B is closed by a membrane, 0. Apipe, Another pipe, b, conveys the gas from the vessel B to the main burners L. Figs. 3 and a show that the ends of the pipes at and b are aligned within the chamber B, and between themis placed a sliding rod, G, having terminal disks g,which Fig. 3 is a detailed top can be thrown alternately against the ends of said pipes a and b. .The rod G is reciprocated by the movement of the membrane 0. To this end the membrane 0 carries in its center a vertical tube, D,whioh is closed at its upper end, and which fits on a pin, K, that projects upwardly from the rigid bottom of the vessel B. WVithin the vessel B the tube D is threaded,

'andcarries two collars, c c,which are screwed upon it at proper distances apart, and which can be adjusted as occasion may require.

In the vessel B is pivoted to a suitablestandard a lever, E, which has a toe, F, that enters a slot in the rod G, the end of the lever E beswings it up until after it has passed thehori- Zontal position, whereupon the springs H H, which are contracted by this movement, will,

in their endeavor to expand, continue the motion of the lever E in the upward direction, until, finally, the rod G is pushedso as to close the pipe a and open the pipe 12. Now the gas escapes to theburners and the membrane sinks, thereby causing the upper disk eV to strike the lever E, until, finally, the rod G will be pushed to close the pipe I) and open the pipe at. As already stated, during the first half of the movement of the lever E the springs H Hare 8 5 contracted. During the second half of the same movement they expand, thereby giving to the rod G a sudden motion and causing a quick closing and opening of the pipes a and 1). Small,

' being moved by the toe F of thelever E.

The chamber B is out off from all communication with the gassupply pipe a, while the pipe bfeeds the burners. In order to obtain the proper burning-pressure, a spring, 0, is

placed on the membrane 0. Thisspringbears upon a flange, an, of the tube D, and is compressed against the upper cap, M, when the membrane is raised, assisting in depressing the membrane at the time the gas escapes to the burners. I11 order to centralize this pressure of the spring 0, we prefer to form the flange m on a cap, 1?, which has 011 itsinner side acentral downwardly-projccting pin that rests on the center of the tube D, as isindicated in Fig. 1. The pipe I) enters a chamber, N, which is formed in the upper part of the cap-like structure M, that carries the burners L, as indicated in Fig. 1, said burners communicating with said chamber N. Right between these burners L is the igniting-burner 2, which receives its supply of gas direct through a chamber, a, and pipe 0 from the regulator or suitable gasreservoir, so that it will always belighted. This little igniting-burner z enters the chamber a, and is screwed into it to greater or lesser depth, according as its lower end is nearer to or farther from the bottom of the chamber a,whieh will admit less or more gas to said burner.

To regulate the duration of the respective periods during which the main burners should be lighted, the gas is first excluded from the pipe at by a screw-valve, Q,wherenpon proper experiments can be made to determine the position of the disks 0.

In order to guard against accidental extinction of the igniting-flame from external causes, we place above it a spiral, It, of platinum, either in form of a fine wire or strip, which is constantly kept glowing by the flame, and which, if the flame should be momentarily extinguished, will serve to relight it so soon as the gas again flows through the burner. This spiral also assists in lighting the main burners L.

XVe claim- 1. In asea-lantern, the main burner or burners L, combined with the pipe I), gas-supply chamber B, and gas-supply pipe a, and with means for alternately opening and closing the specified.

3. The combination of the pipe to with the chamber B, membrane 0, tube 1), disks 0, lever E F, springs H, rod G, pipe I), burners L, pipe 0, and igniting-burners .2, as set forth.

4. The combination of the chamber B, its membrane 0, and tube D with the upper spring, 0, pipe a, and means, substantially as described, for intermittently closing said pipe a, as specified.

5. The combination of the main burners L and igniting-burners z with the platinum spiral B, placed above the igniting-burner, substantially as specified.

6. The combination of the gas-supply pipe a with the chamber B, having flexible wall or walls, pipe I), burner or burners L, pipe 0, burner z, and with means, substantially as described, ior alternately closing the pipes a 11 within the chamber B by mechanism connected with its flexible wall or vwalls, as set forth.
